U74LVC1G240
CMOS IC
SINGLE BUFFER/DRIVER WITH
3-STATE OUTPUT

DESCRIPTION
The U74LVC1G240 is a single line driver with a 3-state output.
The output is disabled when the output-enable ( OE ) input is high.
To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pullup resistor, the
minimum value of the resistor is determined by the current-sinking
capability of the driver.

FEATURES
* Wide supply voltage range from 1.65V to 5.5V
* Inputs accept voltages up to 5.5V
* IOFF supports partial-power-down mode
* Low static power consumption; ICC=10μA (Max.)
